I have an '02 325cic with auto, and while nothing like my '03 330i ZHP, it is reasonably responsive and fun in the twisties. With a heavy foot, it has excellent passing acceleration, but it is no drag racer. My wife had it the local BMW club's car control clinic last weekend and had a blast. I wouldn't be afraid of a 325, especially with a manual, but the autos are fun too.
